Opera palette
Maroon Cabin
Five opera stops with room to breathe — #0065a1 grounds, #018fe2 and #3dacff do the talking, #6abbff softens, #a9d6ff lifts. The analogous bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
